PSI is a high cloud point additive designed for high salinity polyglycol systems. It can improve wellbore stability, lubricity, high-temperature filtration control, plus reduce dilution rates and bit balling. PSI additive is recommended for freshwater to high-saline polyglycol systems. While polyglycols are most effective when used in conjunction with an inhibitive-salt, non-dispersed polymer system, they can be used as additives in most water-base systems. PSI agent is acceptable for most applications specifying specifying low-toxicity additives.

Application/Function

PSI additive has application in polyglycol systems in fresh-to-high salinity make-up water and can be used in wells with high formation temperatures. When used properly, this high-cloud-point additive helps to stabilize troublesome shale by plugging shale pores, preventing the equalization of hydrostatic pressure away from the wellbore.
